I recently got into a bit of a sticky situation with my sister in law. My wife was at work and she asked me to drop off something at her sister’s place. So off I go to deliver said item and she invites me in for a drink because she’s home alone and she’s bored. After maybe an hour or so of chatting I noticed she was gently rubbing my thigh with her foot, this immediately made me rock hard because I have a feet kink. She noticed that I now have a large bulge in my jeans she smiles at me and begins to rub it with her hand. I can’t remember exactly how it happened because it was so fast but before I knew it she was topless exposing her 38GG tits and she had my dick in her mouth. After what felt like seconds we’re both naked and fucking vigorously on the couch after only a few minutes I’m on the edge of exploding and I tell her I’m gonna cum. She shouts at me to pull out and finish on her tits. Afterwards she quickly disappeared into the bathroom and when she came back she told me to leave and that we need to “forget it ever happened” problem is I can’t forget and I want more
